/* glibc 2.34 made MINSIGSTKSZ non-constant. This is a problem for sim
* builds. Hosted targets are using ancient glibc where MINSIGSTKSZ is
* still a compile time constant. On platforms where this is a problem
* (mainly x86-64 and ARM64) the signal stack size can be big, so let's
* give a decent amount of space and hope for the best...
* FIXME: this isn't a great solution. */
